Why was clemency trending last week?
1719, plural of chint (1610s), from Hindi chint, from Sanskrit chitra-s "clear, bright" (cf. cheetah). The plural (the more common form of the word in commercial use) became regarded as singular by late 18c., and for unknown reason shifted -s to -z; perhaps after quartz. Disparaging sense, from the commonness of the fabric, is first recorded 1851 in George Eliot (in chintzy).
